Siemens offers power supply devices for up to 100 W in ultra-narrow design

With the fourth generation of Logo!Power, Siemens has extended its power supply portfolio to include two additional power supply devices as well as additional functionalities and new scope for application. This series of compact devices now comes with a narrower width reduced by 18 millimetres, allowing more flexible mounting, for instance on DIN rails in distribution boards, or directly on walls or ceilings. They can be mounted gaplessly side-by-side with other devices, for instance to supply power to adjacent Logo! logic modules. With efficiency of up to 90 per cent over the entire load range, and no-load losses of less than 0.3 watts (W), these power supply devices offer outstanding energy efficiency both in standby and running operation.

The innovated Logo!Power series with its housing widths of 18 to 72 millimetres is the compact successor to the previous 3rd generation. The new variants with 24 V/0.6 A and 12 V/0.9 A extend the portfolio for very small outputs and come in a width of just one 18 mm pitch. A total of eleven devices with regulated and adjustable output voltages of five, twelve, 15 and 24 volts (V) supply an output of up to 100 W.

Their wide-range input allows these power supply devices to be operated at all single-phase supply networks with 110 to 240 V AC nominal voltage and even at direct voltage networks with 110 to 300 V DC without the need to switch over. For capacitive loads on power supply start-up, a power reserve of 150 per cent is available, and the constant current behaviour compensates for overloads during operation.
